As hard as it may be not to do, avoid from comparing the person you’re dating to your ex-spouse. It’s a recipe for disaster. No one wants to share qualities with someone you are no longer involved with. It’s the fastest way to make them feel defensive. Remember that each person is different. They’re the sum of upbringing, experiences, thoughts, and feelings. Even if the two people you have experience with share similarities, it’s best not to bring it up. You can talk to your current partner about something that bothers you about them. Don’t, however, bring up you ex in the same conversation. It’s off-putting.
